Abstract:

As a result of technological advancements, modern businesses seek new and improved methods of conducting their business processes. Systems have been designed to augment and manage core business functions such as production, accounting, procurement, and human resources. However, even with these systems in place, information is unreliable and inconsistent if they are on disparate platforms. Enterprise Resource Planning (ERP) software tackles this problem by integrating business processes into a centralized system. This paper assesses the stages involved in transitioning form legacy systems to an ERP system. It highlights ERP benefits to businesses, as well as the success and challenges associated with its implementation.
